ADJUSTABLE WINDOW-SCREEN.

To all whom it may concern: Beit known that-I, JAcoB KALMANOWITZ,

a citizen of the United States of America,

residing at Brooklyn, Kings county, State of New York, have invented certain new and v useful Improvements in Adjustable W indow-Screens, of which the following is a full, clear, and exact description.

This invention relates to improvements in Window screens, the object being to provide a window screen that is adjustable both vertically and laterally in order that the screen can be fitted to any window sash.

My improved screen is arranged for,disassemblage or separation into two parts each of which is-a complete adjustable screen for half of a sash or window opening.

I Will proceed to describemy invention in detail the novel features of which'I- will point out in the appended claim, reference being had to the accompanyingdrawing r H I,

' 7 ing subsection 8 (see Flg. 1). The channels wherein z+ Figure 1 is a face view of a window having my improved screen attached thereto;

Fig. 2 is an enlarged perspective view of a' portion of some of the screen members;

Fig. 3 is a similar view of the right corner of the screen members to the right in Fig. 1;

Fig. is an enlarged sectional detail view,

the section being taken on a line 4 4: in Fig. 1;

Fig. 5 is a vertical section, the section being taken on a line 5-5 of the upper subsection in Fig. 1; and

Fig. 6 is a perspective of the right corner, as viewed in Fig. 1, of the screen member to the left in Fig. 1. V 7

My improved screen consists, in this instance, of four adjustably connected members, said members or screen subsections being connected one to the other in a manner to permit of the lateral adjustment of the sections and also to permit of a vertical adjustment. In other words, my improved screen is assembled so that it can be madejto fit window sashes of various widths and also telescoped or extended vertically.

My improved screen consists mainly of two sections A and B, one of which is immovable, the other movable. The immovable section is located preferably in the upper half of the window opening, the lower section being movable so as to cover or uncover the lower half of the Window opening.

subsection 7 consists of an angular corner Patented July 9, 1918.

subsections 7 and 8 while the lower section B consists of the subsections 9 and 10. The

subsections 7 and 8 are slidably connected to permit of a lateral adjustment and the subsections 9 and 10 are also slidably connected for similar purpose. The sections A and B are connected together to permit of a vertical movement of said sections, one upon the other, although in practice the lower section B will be the movable section. I

The upper section A, as has been sta ield,

member 11 turned over at its outer edge to form a vertical channel 12 to slidably receive the angularv corner member 13 of the subsection B. The upper and lower horizontal members of the subsection 7 consist of channel members Hand 15 (see Fig. 5), to slidably receive the upper and lower horizontal members 16 and 17 of the cooperator horizontal members 14: and 15, of the sub section 7, are connected at their inner ends by a vertical channel member 18 (see Fig. 6 to receive a vertical member 19 (Fig. 6) of the subsection 9 of the lower screen section B, the vertical member 19 being the inner edge of the said subsection 9 of the lower section B. The inner vertical members of the subsections 8 and 10 consist of strips 21 and 20 (Fig. 2) respectively; strip 21 connects the inner ends of the horizontal members 16 and 17 of the subsection 8 and the strip 20 connects the inner ends of the horizontal members 22 and 23 of the subsection 10.

The outer ends of the horizontal members 16 and 17 of the upper'section A, are connected by an angular strip 26 (Fig. 3) having a channel 26 to slidably receive the angular corner member 26 which connects the outer ends of the horizontal members 24* and 25 of the subsection 10.

For the sake of clearness, each subsection will be described.v The subsection 7 con sists of the channeled angular member 11,

' nel members 24 and 25 having their inner ends connected by a yertical strip 19 which subsection 8, the horizontal members 2 8' and and at vertical strip"20, \v1iichi con :nects th e'in'ner ends of said horizontal in; here.
